Back in June 2001 there were two posts regarding some of the digital
level options that are out there. You might want to check them out.

People that have purchased their's more recently seem to have the
Macklanburg-Duncan's SmartTool. This is the one that John Kleber points
out does not have alternate zero. That would be a nice feature.

This is the one that they sell through AS&S

I have saw another product that was used in "From the Ground Up" in
building an RV-8, but I don't seem to be able to find information about
it.

I am guessing that the unit you are looking at is the MD Smart Tool
mentioned above. I can't remember seeing a price better than $90 for the
digital module. I did a quick search before sending this response out,
and I found sources with the MD Smart Tool prices at the $90 to $108
range for the module only.
